|
|
T lymphocytes secrete (blank) which can make the fibrous cap vulnerable.

|
Why does MI often occur in the morning?
|
Believed because physiologic stressors are elevated at this time of day.
|
|
True/False - Cocaine decreases SNS tone causing vasospasm, which can lead to ACS
|
False - increases SNS tone
|
|
What is the earliest histological evidence of myocardial irreversible injury?
|
Wavy myofibers
|
|

|
True

|
What is the "pain" time course in AMI? Is it alleviated by rest? effect of nitroglycerin?

|
|
What condition is responisble for many asymptomatic presentations of AMI?
|
Diabetic neuropathy
|
|
What is the effect of reperfusion on CK-MB and cTnI?
|
Washout effect (rapid earlier rise in both)
|
|
True/False - Early invasive approach is most beneficial in patients with high risk features, such as ST elevation, serum biomarkers, or other cardiac RFs.
|
True
|
|
True/False - Patients who recieve thrombolytic therapy within 3 hours of symptom onset have half the mortality rate of those after 6 hours.
|
False - within 2 hours
|
|
True/False - Ventricular fibrillaiton is largely responsible for episodes of sudden cardiac death during AMI.
|
True
|
|
What is the treatment of choice for cardiogenic shock?
